I'm about to throw my tank out the window!
All these chemicals.... So confusing! I'm trying to grow plants, not cook meth!
Ok.. I've got a ten gallon aquarium. It has 2 19 watt screw in PC's in the hood. I'm using a 3 liter co2 bottle with it.
I want to do a 50% water change once a week. We have well water, and it's cloudy and basically has no GH or KH. I want to take 5 gallons of RO water and use that for my 50% water changed. In truth, considering rocks and gravel, The tank probably holds 7 or 8 gallons.
Now.. Lets see.. If i had .06 Tsp. of KNO3 to the five gallons of new water, that should give me a Nitrate level of 10.97 PPM, right? If I add .12 Tsp. Of KCl that would give me a Potassium level if 19.86 PPM, right? I'm also going to add 1 ML of flourish.
This is where it gets SO tricky! For me, atleast.
If I add .28 Tsp. of Epsoms Salt to the 5 gallon bucket of fresh water , I'll get a Magnesium Level of 7.87 PPM. That's good right? How will this affect my GH? Since I'm using RO water, don't I need Calcium, too?
If I add a half teaspoon of Baking soda, Will my KH be in the right range for this five gallon bucket?
Now, after all that is done, Can I add that chemical cocktail to my tank? Will the levels change enough to worry about assuming I do this weekly? What do I do seven days from now? Can I repeat all that? Thats really more like a 60% water change. I'm so confused guys! Please help! I'm no chemist! I've been reading for HOURS and i'm just as confused as ever!
By the way, the only inhabitants are Red Cherry shrimp and 3 ottos. Just got them today (the ottos). I'm running 100 ml's of purigen in the filter if that matters.
I'm growing Ludwigia repens, Ludwigia sp. cuba, Downoi, HC, Anubias and moss, And i'll be getting some green narrow rotala macandra and dwarf lobelia in soon. I'm using shults substrate and sand.
And I've read Rex's guide. It's great, but I'm just in the dark here. I want someone who knows what they are doing to tell me what to do. I'd rather not buy real aquarium products if I get get buy with "ghetto" substances, but I i have to, I will.
